ABOUT ME

iOS developer, Swift compiler hacker, flamewar-starter

I work on the Swift compiler for fun. If you use Swift, you're running my code!

I run an iOS development company. My clients include Fortune 500s, governments, and startups.

I'm a hacker at heart and I like solving difficult technical challenges. I know my way around graph theory, compiler/interpreter internals, algorithm design, computer vision, project management, test design, and much more. Chances are, if you have a problem that can be solved by writing software, I can help.

Believe it or not, I was doing iOS dev even in the jailbreak days. iOS is sort of a very broad field, so it's difficult to quantify how deep my experience goes "as a whole". Being good with say OpenGL is a very different cup of tea than being good with CoreData. What I can tell you is that there are some dark corners of the SDK where I am probably the world expert outside of current or former Apple employees. I've worked on over 50 apps and I've touched pretty much every part of the SDK. I have a great understanding of the technology, but also the organizational practices and processes that lead to creating a successful product.

For a period of time, I maintained a fork of git. It turned out not to go anywhere, but it was a very interesting learning experience.
